Troubleshooting steps故障诊断步骤

①Power on check上电检查

1. Repower the vehicle, use the diagnostic tool to read and clear the fault codes, and check whether the fault codes and symptoms are eliminated.车辆重新上电，使用诊断仪读取并清除故障码，检查故障码及症状是否排除。 Are the test results normal?检查结果是否正常？ Yes是 Fault resolved.故障排除。 No否 Go to step 2.去步骤2。

②Reduce electrical equipment减少用电设备

1. Reduce electrical equipment and re-discharge the vehicle.减少用电设备，车辆重新放电。 2. Stop discharging, restart the vehicle, and read the fault code again.停止放电，重新启动车辆，再次读取故障码。 Are the test results normal?检查结果是否正常？ Yes是 Fault resolved.故障排除。 No否 Go to step 3.去步骤3。

③Check battery pack power检查电池组箱电量

1. Check whether the battery pack power is too low.检查电池组箱电量是否过低。 Are the test results normal?检查结果是否正常？ Yes是 Go to step 4.去步骤4。 No否 Charge the battery pack.对电池组箱进行充电。

④Replacing the integrated electric drive assembly更换集成电力驱动总成
